VA9204-AGA-2Z actuators includes plenum-rated cables and
are specially configured for installation in spaces used for
environmental air-handling purposes other than ducts and
plenums as specified in National Fire Protection Association
(NFPA) 70: National Electrical Code (NEC) section 300.22(C),
Other Space Used for Environmental Air. The space over a
hung ceiling used for environmental air handling purposes is
an example of the type of space for which these actuators are
configured.
IMPORTANT: Use this VA9204 Series valve actuator only
to control equipment under normal operating conditions.
Where failure or malfunction of the VA9204 Series
valve actuator could lead to personal injury or property
damage to the controlled equipment or other property,
additional precautions must be designed into the control
system. Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit controls,
intended to warn of or protect against failure or malfunction
of the VA9204 Series valve actuator.
